l Be it known that We, CHARLns E.l GAFFN'EY and` JoHN R. Perfuman, citizens,- of the United States, residing in the city" ofv St.

Louis and State ofMissouri, have invented a new and useful Hot-Water and Vacuum Cleaning System, of which the following is his inventionrelates tohiot Water and vacuum cleaning systems, and its prime object is to provide va vacuum clear'nng-apparatosv combi-ned directly with'a hot water heater, lwhereby .a `single generator or heater may be. used for Supplying hot Water, and

for creating steam pressure'for a vacuum creating element in the vacuum cleaning apparatus.y

There are other objects to be attained'by the resent'invention, which will be appar.-v ent rom the following detailed description, reference being made to the accompanying drawings in Which- .Figui-el isa side View, partially in `section, showing the complete syste-rn; and' Fig. l is a lsectional vievv'through the line 2-2 ofl Fig. 1, lshowing the back-pressure valve,

and Ithe 'connectionstherefrom to the valvel in the fuel supply pipe. l

The water tank 1 is supplied with Water through the pipe2, which is connected .to

a -Water supplyl main pipe 3. The Water inv .the tank 1 is supplied to the generator or heater 4-through the pipes 5 and' 6. It 4Will be apparent that since the Water supply tank 41 is elevated above the highestvwater level in the `generator or heater 4 the `hydro-.

static pressure will be suiiicient to maintain Water, lunder'pressure, .in said generator ory heater 4, at all times. vThe passage ofvwater from the pipe 3 to the vpipe -r'isfcontrolled .by a. valve 7, which valve' is .heldnormally .closed byan expansions spring 8, encircling a pin 9, "which pi projects' throughl the -valve case 10. V

A fuel'supply pipe 11 supplies fuel of a` liquid orgas'eous character to aburner 12,y

supportedadjacent tothelower'part of the generator or heater -4. Theys'a'id burner 12 is provided with a plurality of )ets 13,;Wh1ch Vare suitably .disposed-in suche manneras 4. A pilot light 14 may `be provided for `igniting theA fuel is admi ted thereto.'

getal?) of the burner 12, when' The generator or heater4 and the burner 12 are inclosed in a' housing orhood 15, which We prefer to make of two separated vvalls., Wit-h an air spacebetween, as shown in- Fig. v1, thus preventing radiation as far as possible. The housing or hood 15 is supported in 'any convenient manner, and We `have here shown it mounted on a stand'l of'usual'construction. `Itis obvious that the -housing'or .hoodv 15)' may be disposed with, but in practice it' has been found to be advantageous for confining .and equali-zing the heatsupplied to the generator or vheater4. The housing or hood 15 has a flue 17 leading from the top thereof, which is effective as Aagineans for egress for the gas and fumes .,fnm' the burner 12.- This tlue 17 maybe provided With `a damper 18'of usual type. by vwhich the draft may be regulated. We have illustrated a generator or heater `4 of preferred construction for use in the present system. -The generator'orheater 4.l

comprisesa plurality of circular hcflow chambers 19 supported in oblique adjustment., as clearly shown in Fig. 1 of the drawing. Each of the units 19 has severalpassages 20I therethrough, permitting the heat from the burner '12 to rise and be dis'- tributed uniformly throughout the gfi'ierv 85 'ator Ior vheater4. The units 19 are connected yby interconinninicating passages 2,1, so that the circulation of Water orsteam will be continuous, and free. A valve controlled pipe 23 attached to the lower port-ion of the generator or' heater 4, is for use -in cleaning or draining the system. ininating in a valve or .faucet 25 is provided A -pipe 24, ter! specieatdn of Letters raient. Patented Feb, 13, 1913 for drawing off hot water frointhe' genere` atoror heater .41 .It -Will be understood thatm.

any other' type. or design' ofvv generator mayv 'be-used, and lthat a full system of piping `may be used' instead ,o f t'l'iesingle pipe 24, whereby water may be supplied throughout a building. v

The fuel supply pipe .l1 is controlled byv 'a valve 2G, which isy actuated toward closed adjustment by means of a spring-27, 4 encircling a pin QS.` `The pin 28- terminates adjacent to the pin 9,` and coperates there with to open the valve '26, when the wilveA T is 'openedby the pressure of the Water in the pipe 3,. .'Said valve 26 maybe independently operated by means' ,of a draai' chain'.l Q9, which passes over a sheavetiO..`` It isap'p'ar- 'pent lthat the draw chain"29layteranine'tegico ,les

vandbe operated from .any desired location in thebuilding in which the system .may be installed. Between saidA valve 26 andthe .'uelburner12, We provide an auxiliary valve 31,' which is regulated through lever and link connections by 'pressure in the pipe 6.

it isobvious that when the pressure in the .l generator or heater 41s increased to Asuch a -point as Will overcome the tension of the Lao.

spring 32, the piston 33 will be raised, therelJy/,regnlating through the lever and link' connection the amount 'of fuel that may pass fluough the valve 31.

The'tension of the spring 32 .may be adjusted, so that the gen r or heater el. may carry any predeined haelt-pressure, above which the i alte 31 will operate. In this way a uniform steam pressure in the generator or heater-ft` may: be malntalned, and substant1ally-un1- l form 'temperature may be preserved therein.

The upper end of the generator or heater t opens into a globe chamber 34, which come inunicates by meansof the passage with the valve'A chamber 3G. A by-pass connec- ,tioiif is proyided between said passage 35 andthe Water' supply tank l. The valve ehalnber 3G' is provided with aremovable top36f",'having a` tubular extension 38, 1n which there is a 'tapering passageV 39. A

i 'ioat device t0-within the valve chamber 36 has apointed .projection tl extending intothe passage and constitutes a valve, which 4 is normally closed and is effective to prevent any'flow of water through said passage 39, since the water Within the valve chamber upholds the llioat,.and' presses the projection 41 into.. the passage' 39, thereby closing said passage.' When steam is generated and rises into the valve chamber 36, the level of the Water in said-chamber lowers, and the float ,lill automatically lowers with the water stitutes a discharge pipe into and through` which the particles brought in through lthe pipe 45 will be discharged by t-he pressure or draftfroni the ejector or aspirator 43.

From the foregoing it will be understood' that the tank l'is filled from the main water supply 3, andthat the generator or heater l is supplied with water at'uniform pressure through the pipev connection 5 6,

and that the valves 7 25, 26, and 39-41 are normally closed.. In operation for heating water the valvf. 25 is opened, which automatically causes the valve 'l to open, and the stem 8 to abut against Aand press against the stern 28 of the valve-.26, thereby causing Said valve' to open and permit the passage .of fueltherethrough to the burner 12. The

jets 13 of the burner l2 are ignited by the pilot light and the water continues to circulate through the generator or heater 4, be coming rapidly heated in its tortuous pas* sage. therethrough. In generating steam, the valves 7 and 25 are closed, The generator'or heater 4C is supplied with water, at uniform and constant pressure, from-thc supply tank l. lVhcn the water in the generator has heated to a sutlieient degree to develop .steam the valve 39-1l1 automatically opens, and steam escapes through the ejector or aspirator 43, causing a .strong draft or suction in the pipes 4st and 45. The auxiliary valve 31 is operated by the backpressure of steam in the generator. When the pressure increases above a. certain point a closure or partial closure of the' valve 31 is effected, thus reducing the amount of fuel supplied to the burner 12, thereby causing the temperature in the heater or generator to fall, and the pressure to be reduced, causing the valve 3l to again open. Since the valve 31 is mthus balanced, it is apparent that a constant and, uniform pressure of ,steam will be maintained in the heater. The amount. of fuel that passes through the valve 26 is regulated so that it corresponds to the quantity of water that passes through the valve 7. It will be observed tliereforatthat when the .quantity of w .ter drawn freni` the pipe A24 is increased, tie supply of Water passing through the valve 7 .to supply the generator or heater must necessarily increase. When the system of piping in a building supplied by our present. system includes a plurality of valves, instead of the single valve 25 a greater quantity of water may be drawn at one time, and the fuel supply for heating this increased supply will be relatively increased. Thus it wlll be seen that in our system only the requisite amount of fuel to heatV a given vquantity of water to a given temperature will besupplied, and no loss of heat will occur.

l/Ve are aware that several minor details in arrangement, construct-ion, and design of .the parts may be made, Without departure from thc spirit and scope of our invention, we do lilnit-y ourselves, therefore, to exact details, but
